Garmin Astro 430/T Review-GPS Tracker For Hunting Dogs


If you take your hunting dog to large parcels of land to hunt, you need a GPS Tracker for hunting dogs to keep track of them.

This Garmin Astro review will take a look at the features of the Garmin 430/T and reviews of other hunters that have used this GPS Tracker. This should help you decide if this is the dog tracker that you need.

The Garmin Astro Tracker 430/T

Garmin has been specializing in GPS technology since 1989, and has been the leader with the newest technology available.

The Garmin Astro 430/T is the latest generation for GPS/GLONASS tracking for sporting dogs yet. They have improved upon their Astro 320, and have created their best dog tracker to date.

It has the expanded dog capability to track up to 20 dogs from a range of up to 9 miles. That is while giving virtual real-time updates for all your dogs. The screen refreshes at a 2.5 second update rate, providing the fastest tracking available which helps for dogs on the run.

Garmin uses GPS/GLONASS technology, which is a high sensitivity GPS and GLONASS satellite reception. It has the ability to track in more challenging environments than GPS alone.

This system can track even where there is no cell phone coverage or internet, so you have the piece of mind that it will work even in the most remote areas you may be hunting.

Overall Opinion

Because of the number of features, the durability and the simplicity of use, I do recommend the Garmin Astro 430/T.

Having the piece of mind to know where your dog is at all times can allow you to calmly let them have fun, but be able to find them when you need them back.

I only found positive reviews in regard for working in areas that are dense and mountainous. You can read the reviews from customers here if you are interested.

There is a complaint about the GLONASS satellite not working outside of the U.S., which I mentioned above in the cons.

Overall, I think it is a great dog tracker for sporting dogs, or dogs that have large areas of freedom.


If you have hunting dogs, which means they need to run free, the best thing you can do for yourself and your dog is to get a GPS Tracker for hunting dogs.

From this Garmin Astro 430T review, you should see that there are more features than many of the other trackers available, allows you to track up to 20 dogs, up to 9 mile range, and will work even where there is no cell service or internet service.

Many of the less expensive trackers are not going to provide you with the security that this Garmin Tracker can.

GPS technology is what Garmin specializes in, so why not go with the specialists and have the security of knowing it will work when you need it most.
